You're a good momma, Sox!! I can tell Molly has gotten a great home.
When my cat had a UTI I practically camped out by the litter box so I could be sure that he was going and that he was going as much as he should be. He was on medication but I wanted to be sure - animals can go from bad to worse is a very short time frame when it comes to UTI's.
Molly will become one of your kids - and you'll worry about her as much as you do the human kind!!
